Some redmine users also like to submit tickets from alternative or personal email addresses, and an ideal enhancement to the email submission would be:

1) possibility to add email aliases in addition to the default email address that is used for sending notifications. this way, an email from the default address or the secondary alias address will be accepted.2) possibility to allow ticket submission from a previously unknown address. this could be mapped to a default generic user, or a new username created from the email address (both options could be avaialable to the administrator).

create: a user account is created (username/password are sent back to the user)

Permissions have to be consistent with the chosen option. Eg. if you choose 'create', the 'Non member' role must have the 'Add issues' permission so that an issue can be created by an unknown user via email. If you choose 'accept', the 'Anonymous' role must have this permission.

History

I added some functionality that might be interesting. Basicly some more options for receiving e-mail, like what do to with unknown addresses. it's a little bit configurable like i thought it could be usefull.A new user will be created from the email address:

If you plan to put this issue in 0.9, it would be a really good idea to allow anonymous tickets with an email adress attached. This way, you are not forced to have every email to create an user only to know who has created the ticket. Kind of light users only with an email adress and unable to log in. Think of redirecting your webmaster@domain.com into redmine... and btw: there is a patch to activate a permission called "view own issues" - perfect solution for inbox projects.
